Very little is known about this company. Apparently, UA Limited was the software company that created games for the Emerson Arcadia 2001 game system. In the late 90's, it was discovered that three of their games had been ported to the 2600. Cat Trax showed up on a European multi-cart (where it was called Cat and Mouse), and both Funky Fish and Pleiades prototypes were discovered by a collector and ultimately purchased by AtariAge. We have released the binaries to both Funky Fish and Pleiades and made all three games available in cartridge form, complete with boxes, manuals and labels.
